Lung-resident memory T (T) cells respond rapidly and effectively to respiratory pathogen invasion, suppressing pathogen proliferation. Previously, we identified a defined TLR3 agonist called Nexavant (NVT) and developed a vaccine platform that utilizes it to induce lung T. In this study, we aimed to determine whether the protective effect of T cells is observed in tuberculosis (TB), a chronic bacterial respiratory disease.

M1 macrophage polarization is modulated by the release of mitochondrial DNA (mtDNA) and induces the inflammatory immune response, which is further increased by the generation of mitochondrial reactive oxygen species (mtROS). The pyrimidine nucleotide carrier SLC25A33 is located in the mitochondrial inner membrane and is linked to mtDNA synthesis, but its role in the M1 macrophage inflammatory immune response remains unclear. Here, we elucidate the regulatory mechanisms responsible for upregulation of SLC25A33 expression during M1 macrophage polarization, SLC25A33-mediated mtROS production, and the inflammatory response.

Antibody-recruiting molecules (ARMs) have emerged as a promising strategy for enhancing immune responses against pathogens and cancer cells. In this study, we developed a novel class of antibacterial ARMs utilizing siderophores, small iron-chelating compounds, as targeting motifs. Siderophores naturally exhibit high specificity for bacterial pathogens due to their role in iron acquisition, making them ideal candidates for selective targeting.

Unlabelled: Following reactivation of a latent alphaherpesvirus infection, viral particles are assembled in neuronal cell bodies, trafficked anterogradely within axons to nerve termini, and spread to adjacent epithelial cells. The virally encoded membrane proteins US9p and the glycoprotein heterodimer gE/gI of pseudorabies virus (PRV) and herpes simplex virus type 1 (HSV-1) play critical roles in anterograde spread, likely as a tripartite gE/gI-US9p complex. Two kinesin motors, kinesin-1 and kinesin-3, are implicated in the egress of these viruses, but how gE/gI-US9p coordinates their activities is poorly understood.

Lung tissue-resident memory T (T) cells induced by influenza vaccination are crucial for heterosubtypic immunity upon re-exposure to the influenza virus, enabling rapid and robust responses upon reactivation. To enhance the efficacy of influenza vaccines, we induce the generation of lung T cells following intranasal vaccination with a commercial influenza vaccine adjuvanted with NexaVant (NVT), a TLR3 agonist-based adjuvant. We demonstrate that intranasal immunization with the NVT-adjuvanted vaccine provides improved protection against influenza virus infections by inducing the generation of CD4 T cells in the lungs in a type I interferon-dependent manner.

Cancer cells use multiple mechanisms to evade the effects of glutamine metabolism inhibitors. The pathways that govern responses to alterations in glutamine availability within the tumor may represent therapeutic targets for combinatorial strategies with these inhibitors. Here, we showed that targeting glutamine utilization stimulated Yes-associated protein (YAP) signaling in cancer cells by reducing cyclic adenosine monophosphate/protein kinase A (PKA)-dependent phosphorylation of large tumor suppressor (LATS).
